I needed to mount an .iso file this morning, which I’ve done dozens of times in Linux, and I realized the command I’d normally use in Linux does not work. For example: Linux mount -o loop image.iso /mnt This works fine in Linux and lets you “mount” the .iso file as if it were burned… Read More »

I’ve been spending a lot of time lately researching FreeBSD security solutions. Topics such as pf (packet filter), system hardening, etc. One of the tips that I thought I’d share here is a method of configuring your system to use blowfish encryption for passwords as opposed to the default MD5. If you are on a… Read More »

I’m looking for some good pf (packet-filter) documentation if anyone has anything to suggest. I’ve added a second FreeBSD machine to my public-facing network, and may be adding a third soon. I want to make sure that my firewall is setup properly but I’m not very familiar with pf. Can anyone suggest a book, online… Read More »

A friend of mine shot me this article today (What’s cooking for FreeBSD 8?), which is a pretty detailed outline of the things coming up for FreeBSD 8. I have to say, some of the things have got be excited! Some of the highlights that I want to see: Parallel Ports Build (announcement) Jails v2… Read More »

[SA-09:06] Limit the size of malloced buffer when dumping environment variables. [EN-09:01] If you’re interested in applying this update to your system, here is the method I… Read More »

Not so long ago I wrote about how you can configure FreeBSD to email you regarding available updates on a weekly basis. This is something that I have had in place for a while now, and I really enjoy the ability to keep things on the patched (read: bleeding) edge. Recently I found a small… Read More »

I love FreeBSD for how efficient and minimalistic it can be. For my web servers I like to add to this efficiency by using Lighttpd instead of the larger, older, Apache. The one little issue with Lighttpd vs Apache is getting all the same module support setup for all the little tweaks that you’ve come… Read More »

Update: I have suggested a minor improvement to this setup. Read More… For some time now I’ve been maintaining about a dozen FreeBSD jails, each running a different set of services. Everything from email to BIND, DHCP to nagios. One of the difficulties of trying to maintain so many servers has been tracking and applying… Read More »

I have had all kinds of problems getting dhcpd running properly inside a FreeBSD jail. I finally got it running this morning and wanted to document what I’ve done in hopes that I can recreate it. On the host system I had to allow sockets within jails. This is done by adding this line to… Read More »

I spent some time this afternoon on the bus ride home setting a new theme to the blog here. I’ve also cleaned up the categories. Ohh, and the most exciting part (even if it is transparent to the end-user), I upgraded to WordPress trunk. If you have not seen the new dashboard in WP 2.7… Read More »
